As National Signing Day continues to unfold, Texas A&M appears to be on its way to signing another top 20 class.

Here's a deeper look at the Aggies' 2018 class:

Head of the class: Leon O'Neal Jr., safety

Signing O'Neal was something A&M's old and current staff fought hard to make happen. In the end, O'Neal chose A&M over the four teams that made this year's College Football Playoff. O'Neal was a vocal leader for the Aggies during his first commitment, selling A&M hard for the school. His re-commitment two days before National Signing Day also helped produce a trickle-down effect, which led the Aggies to gain big wins on the recruiting trail on Wednesday.

Diamond in the rough: Caleb Chapman, wide receiver

One of 10 signees for A&M in the Early Signing Period, Chapman soared up the rankings following impressive junior and senior campaigns at Clear Brook, and was ultimately tabbed as a four-star player. The Aggies need depth at outside receiver, and Chapman's frame (6-5, 210) provides A&M with an option that can match up with SEC secondaries.

Biggest need met: Defensive End

A&M was thin at defensive end in 2017, and the Aggies lose three position players here. Fortunately for the Aggies, they signed three defensive ends in the 2018 class - Bobby Brown, Max Wright and Tyree Wilson - and could potentially ink a fourth on Friday in Dorian Gerald. While it remains to be seen how much each will contribute next season, it is a positive sign for A&M that there is at least depth at defensive end.

Biggest need not addressed: Linebacker

While the Aggies had better play at linebacker overall in 2017, it still has room for improvement and continues to lack depth. A&M did not get any help to add to the depth chart either, signing zero linebackers so far in the 2018 class. The Aggies lost their only LB commit, DaShaun White, after Kevin Sumlin's dismissal, and were unable to ink in-state products Alston Orji (Rockwall/Vanderbilt) and Bumper Pool (Lucas/Arkansas) to address this need.

Class Grade: B+

A&M recovered well from a coaching change and the Early Signing Period, as Fisher & Co. closed on a handful of their top targets after non-stop work on the recruiting trail during January. The Aggies were topped by Texas in the rankings, but their finish in the 2018 cycle has for now set up A&M to be the team to beat in recruiting in 2019.
